Swift Bitwise operators allow you to perform operations on the binary form of numbers. You can specify a binary literal by prefixing the number with 0b, so for example 0b110 is equivalent to the binary number 110 (the decimal number 6). Each 1 or 0 is a bit in the number. Bitwise NOT ~: var number...

Overflow refers to what happens when an operation would result in a number that is either larger or smaller than the designated amount of bits for that number may hold. Due to the way binary arithmetic works, after a number becomes too large for its bits, the number overflows down to the smallest p...
